Letters Patent No, 83,658, dated November ,3, 1868.

IMPRovnn @an To all whom 'it 'may conce/rn Be it known that I, C. T. PHILLIPS, of Jordan, in the county of Onondaga., and State of New York, have invented a new and improved smut-Mill; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled 1n the art to make and use the same, reference being had to the accompanying drawings, forming part of Figure 1 isa side elevation of vmy invention, and Figure 2 is acentral vertical section.

Figures 3 and 4 are detail views.

Similar letters of reference indicate like parts in al1 ,The grain is fedinto the small feed-spout A, and falls through a central opening in the cap O, lig.'2, to the scouring-cylinder D. Ou reaching the bottom of the seeming-cylinder, the grain passes out of the spout E into the vertical blastspout F, and falls to the. ground.

The other end, G, ofthe blast-spout takes a portion oi the d irt 'om the grain as it falls from the feed A to the screen B. The screen B then removes a fur# ther portion of the impurities, and the grain falls into the scouring-cylinder D, where it is scoured,and the dust drawn through the slots or perforations of the formed by the shell H. The grain then passes into the vertical spout F, and in fallingto the ground encountersa' strong upward current of air in F, which rethe blast-spout, is produced by the lar e suction-blast wheel I; this wheel draws `air from e chamber J, hg. 2, and this chamber connects with a chamber, K, by legs Vor side spouts 7c,- iig. l, so that the wheel I draws its lair from the main spouts midway between the two terminations F G. This wheel, I, expels its air from the discharge t, iig. 1.

The suctionjthrough the slotted sides of the scour ing-cylinder D is kept up by a separate blast-wheel, L, the supply of air for this wheel ilowing in through the cap at ,0, fig. 2, and is expelled :tt-discharge l, l. 'lhe 'scouring-wheelM, iig. 2, and both .of the blast-wheels L I, are secured all to the same shaftm. By using an intermediate or separate blast, L, between the suction-spouts G and F, the scouring is more thoroughly done, and the grain is not broken by the scouring-wheel M, as the blast L keeps the grain well of wheat are also saved for feed, as the blast-wheel throws them out with the fine dust, and they are readsiniilar to that shown by the valves 5,) instead of being blown away, as usual.

. The screen B is vibrated by a cam on the shaft m, which rotates in a collar, n, that is rigidly secured to the s'creen B. The upper riddle fr of the screen, is of ordinary construction, -being ofperi'orated sheet-metal; but I construct the lower riddle It by a series of round rods arranged parallel to each. other, Vwith a narrow space between them, as shown by lig. 4. The bars areA secured to a cross-plate underneath, at each end, andthere are no cross-bars or obstructions on-the upper face of the riddle. This construction of riddle gives a much better result than the ordinary construction. rlhe kernels of grain, on falling upon it, arrange themselves longitudinally with ther-ods, and then fall through the narrow spaces ofthe riddle; and in this manner it is necessary to have the openings only equal 'the grain will not pass through. The screen B discharges its dirt at b.

The inner siniace oi' the Scouring-cylinder is indented at each slot, as shown by c in iig. 3. These indentations delay the fall ci the grain down the walls of the cylinder. And said inner surface is also providedwith ribs 'or narrow shelves d, which further delay the passage of the grain, and keep it longer under the action of the scouring-beaters M. l have found that the shelves or ribs d, used in connection with the indented slots or peiforations, give a muchrl better result than ribs and slots not indented, or with indented slots wit-hout ribs, neither of which I claim, as both have been used before.

I am also aware that the several devices herein de scribed, and mainly, also, their combination, are not new, and I do not therefore claim any oi said devices separately, nor their combination; but

The arrangement, herein described, of the seemingcylinder D d c, annular chamber It, blast-wheels L I, screen B R r, chambers J K, conduit-s k, and spouts F G, all operated as shown, and for the purpose specified.

The above specification of my invention signed by me, this 6th day of August, 1868. I

O. T. PHILLIPS.
